He said some crew members who worked at the scene knew the victim.
Firefighters helped St John at the scene with CPR on the victims and also tended to burns, he said.
In situations like this, Bennetto said they often had a debrief and kept an eye on each other's "mental wellbeing".
Often with fatalities, and especially when young children were hurt, he said it was not easy on the crews.
"The effect is quite a bit bigger when children are involved."
He said the death would rock the tight-knit community.
WorkSafe issued a statement today saying they were notified of the electrocution and understood the victim may have been felling trees.
"We are making initial inquiries to establish what our next steps will be," the statement said.
A St John spokeswoman said staff were also called to the incident and sent three ambulances, a rescue helicopter and a manager to the scene.
"We have assessed and treated one patient, who has been flown to Waikato Hospital in a serious condition."
Worksafe was notified and the man's death had been referred to the coroner.
The incident happened on Ngatira Rd near Redwoods Rd and Fly Rd.
